Planning.

Thinking deeply about your request.

Creating execution plan.

Setting up the plan.

Working on your request.

Creating a concise response plan.

Your goal is to turn this into a complete solar-powered EPS schematic.
  • I’ve prepared a plan covering:
    1. Solar inputs, inhibit, and protection
    2. Battery, BMS, charger, and main power bus
    3. Rail generation, switching, and monitoring
    4. Control/telemetry and external connector integration
The plan is ready to execute. Click Start on the plan bar to build it, or tell me what you want changed first.
Plan
#Goal
  • Create a complete schematic for a solar-powered EPS-style power system that includes the following: four solar panel inputs, a deployment inhibit input, solar input protection stage, a 3S Li-ion battery pack interface with BMS connection, battery protection and fuse path, a solar charger stage (with MPPT-set and feedback-setting resistor networks), a battery/system power bus, two buck-derived rails, a 3.3V rail derived from the 5V rail, power-path enable/inhibit switching, current/voltage monitoring, an MCU control/telemetry section, and a PC/104-style stack connector exposing the required rails and control/data signals. The design should preserve the user's named nets and overall block relationships as provided.
#Implementation plan
  1. Create the Solar Input and Protection Stage
    1. Place four dedicated solar panel input nodes as per the user architecture and label them accordingly.
    2. Add a deployment inhibit input and integrate required protection components for solar inputs.
    3. Integrate solar input protection components to manage overvoltage or reverse polarity conditions.
  2. Implement the Battery and BMS Interface
    1. Create a circuit section for the 3S Li-ion battery pack interface.
    2. Integrate a connection for the Battery Management System (BMS), battery protection circuitry, and a fuse path for safety.
  3. Design the Solar Charger Stage
    1. Insert a solar charger stage that includes MPPT control.
    2. Add MPPT-set resistor network and feedback-setting resistor network for accurate regulation.
  4. Build the Power Bus and Rail Generation
    1. Design a central battery/system power bus to distribute power.
    2. Create two buck-derived rails from the power bus.
    3. Generate a 3.3V rail from the 5V rail, ensuring proper regulation.
  5. Integrate Power-Path and Monitoring Features
    1. Add enable/inhibit switching for power-path control.
    2. Include current and voltage monitoring circuits for system supervision.
  6. Incorporate the MCU Control/Telemetry Section
    1. Add the STM32F411CEU6 as the MCU control unit.
    2. Connect the MCU to control and telemetry circuits ensuring full monitoring and control of power functions.
  7. Add the PC/104-Style Stack Connector
    1. Insert a PC/104-style stack connector into the schematic.
    2. Expose the required power rails and control/data signals through the connector.
  8. Preserve User Naming and Block Relationships
    1. Verify that all nets are connected using the user's designated names.
    2. Maintain and organize the overall block relationships as specified by the user's architecture.
#Success criteria
  • The schematic integrates all key parts of the solar-powered EPS-style power system including solar inputs, battery/BMS, charger stage, power rails, and monitoring/control circuits.
  • All user named nets and block relationships are preserved without conflicts.
  • The design is complete, clear, and ready for further PCB layout and simulation tasks as part of production-grade hardware design.
Use STM32L431 instead
Keep exact net names
